Your easiest solution is to click on your camera name in the top left corner of the main viewing window. From there, choose "Set Position To" and you can choose to set the current camera to one of the other cameras (I often use the Top view if I get my camera out of whack).

You can also just select an item and hit the zero on your keypad and it will zoom to that item, which should at least get your camera back to somewhere you can use it.

I gotta admit; this is one of my peeves with Carrara. Many parts of it - the view port / camera name in the upper-left being a prime example - that is completely unintuitive. Until someone actually shows you that it can be clicked on and changed...who would think to try clicking on it?

This was one of the first things I noticed in Carrara, and one of the things I really appreciated over Poser.

That's the way it goes sometimes, one persons obscure is another persons blindingly obvious.

(By the way, there's no such thing as intuition, only common learned responses and pattern recognition. Once you learn that, then all software interfaces fall into place logically. And it is in the manual).
